RELEASE MECHANISM FOR AWNING-TYPE WINDOWS.

Application filed June 22, 1925. Serial No. 38,642.

To all whom it may concern:

Be it known that I, JOHN J. DONOVAN, a citizen of the United States, residing at Oakland, county of Alameda, and State of California, have invented new and useful Improvements in Release Mechanism for Awning-Type \Vindows, of which the following is a specification.

This invention relates to an operating mechanism for awning type windows such as disclosed in my United States Letters Patent, No. 1,541,123, entitled Swinging windows, issued to me on June 9, 1925.

In general the window structure disclosed in this prior patent includes a pair of swing ing sashes which are pivotally and slidably mounted in the frame. This pivotal and sliding connection includes a pair of fulcrum links which are pivoted intermediate the ends of the sashes and to the frames. The upper ends of the sashes are fitted with sliding shoes which slidably engage the jambs of the frame. A connecting member is provided which normally forms a connection between the sashes so that they may be operated in unison. This connecting member is operative so that it may be released from one of the sashes to permit the sashes to be operated separately.

The present application is more particularly concerned with means for Operating this connecting member and it is the principal object of the present invention to provide generally improved means for operating the connecting members of Window structures such as referred to, which means is simple and inexpensive in construction, positive in operation, and capable of being easily installed.

In carrying out this object, I provide pivotal operating levers mounted on the stops of the window frame and adapted to turn parallel to the surface therefor. These levers are connected with the connecting members of the window mechanism by operative connections located beneath the stops and which, upon oscillation of the lever, will operate the connecting members to connect the sashes ordisconnect them, as desired.

One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawings, in which: I

Fig. 1 is a side elevation of a window with the jamb removed to disclose the invention applied to the operating mechanism of the sashes.

Fig. 2 is a vertical section through a win dow disclosing the sashes disconnected from each other and with the inside stop of the window removed.

Fig. 3 is a perspective view of my improved mechanisni for operating the travelling bar of the window.

Fig. f is a large fragmentary view in ver tical section through the stop and operating mechanism disclosing the construction ofthe latter.

Referring more particularly to the accompanying drawings, the window embodied in the present invention includes a frame 10, and a pair of swinging sashes 11. These sashes, is shown in Fig. 1, are offset with relation 1) each other so that the sides of the contiguous rails 12 of the sashes abut. The upper end of each sash is fitted with a pair of horizontally extending trunnions 12* which are slidably received in metal lined vertical grooves 13 formed in the faces of the jambs of the frame.

A pair of fulcrum links 14 is pivotally connected. to the sashes intermediate the ends of each sash and to the jambs. This mounting of the sashes permits opening thereof by merely pushing outwardy on their lower ends.

To connect the sashes, I provide a pair of travelling bars 15 which are disposed upon opposite sides of the sashes and in the same plane as the fulcrum links 14, this being substantially flat of the jambs and beneath the stops 9. These travelling bars 15 are offset as shown in the drawings and are pivotally connected at their upper ends to the trunnions of the upper sash. From this point they extend downwardly so that their lower ends will be contiguous to the trunnions on the lower sash. The offset formed in the travelling bars 15 permits them to operate in a vertical direction.

At their lower ends the travelling bars 15 are formed with horizontal slotted openings 16 so that they-may be engaged with the trunnions of the lower sash to connect the sashes together and cause them to operate in unison. When such engagement has been effected, when one sash is moved, the other moves in unison therewith.

In order to permit one window to occupy a position different from the other, I provide means for operating the travelliiig barslo whereby they may be engaged with or disconnected from the trunnions of the lower sash at will. It is with this operating means that the present application is more particularly concerned.

It should be stated that one operating mechanism is provided for each travelling bar and are consequently located upon opposite sides of the sashes. It is to be understood, however, that the window may be fitted with but one travelling bar to connect the sashes and in such case but one operating mechanism is necessary.

Reference being had to Fig. 1, it will be noticed that each operating mechanism comprises a bearing plate 1.7 which is secured to the jamb of the frame beneath the Stop. An operz ting clip 18 is pivotally connected to this bearing plate for swinging movement parallel to the surface of the jamb. The upper end of this clip is bent back upon itself to embrace the adjacent travelling bar and to abut against the outer edge thereof so that swinging movement of the clip 18 about its pivotal point will oscillate the travelling bar and connect or disconnect the latter from the trunnion of the lower sash. The travelling bar 15 is slidably received by the clip 18 and is free for vertical reciprocation at all times so as to unhamper the operation of the sashes.

The lower end of the clip 18 is formed with a horizontal lug 19'which is connected with a vertical reciprocable operating rod 20. The lower end of this operating rod connects with an operating cylinder 21 which extends transversely through the window stop and supported therein and in an escutcheon plate 22 secured on the outer surface of the stop. It will be noticed from the drawings that the lower end of the op erating rod 20 is bent parallel to the axis of this operating cylinder and engages an eccentric recess therein so that rotating movement of the operating cylinder will vertically reciprocate the operating rod. This movement of the operating rod will be converted into swinging movement of the operating clip 18 and consequently oscillate the connecting bar about its pivotal point and connect or disconnect the latter from the trunnion of the lower sash.

To revolve the operating cylinder 21, I provide an operating lever 23 which is located exteriorly of the stop 9 and escutcheon plate 22 for swinging movement parallel to the surface of the stop. This lever is formed with a key lug 24 which engages a recess formed in the outer end of the operating cylinder 21. The lever is rigidly connected to the operating cylinder 21 by a screw 25. It is intended, however, that the travelling bars be in a position normally connecting the sashes. For this reason I mount flat springs 26 behind the stops 9. These springs are interposed between a shoulder on the frame and the travelling bars and constantly exert a pressure on the travelling bars to maintain their lower ends in engagement with the trunnions on the lower sash.

To insure engagement of the travelling bars 15 with the trunnions on the lower sash, the lower ends of the travelling bars are formed cam shaped as illustrated.

In operation of the present invention under normal circumstances, to open the sashes it is only necessary to exert a pressure on the lower end of one sash. The sashes will then swing outwardly in unison to any. desired angle of inclination. The sashes will be frictionally held in any position in which they are placed.

If it is desired to open one of the sashes, the operating levers 23 are swung about their pivotal points to draw the operating rods 20 donuiwardly, this will swing the upper end of the operating clips 18 inwardly and oscillate the travelling bars 15 about their pivots, consequently disconnecting their lower ends from the trunnions of the lower sash. The sashes may then be operated independently of each other as described.

It is obvious that when the levers 23 are returned to normal position, the operating rods 20 will be moved upwardly and consequently swing the upper ends of the operating clip 18 outwardly, permitting the springs to move the travelling bars 15 into engagement with the trunnions on the lower sash. This forms the operative connection between the sashes so that they may swing in unison.

It will be noted that the operating mechanism is all concealed beneath the inside stops 9 of the frame and therefore do not detract from the appearance of the window.

From the foregoing it is obvious that the present operating mechanism is simple and inexpensive, positive in operation, easily installed.

lVhile I have shown the preferred form of my invention, it is to be understood that various changes in its construction may be made by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.
